Here are the instructions for setting up a UHF remote for TV1:
NOTE: Steps 1 through 7 to be completed with your current TV1 (IR/Infrared) remote.
Go to the room where the 522 is, turn on the TV and TV1 tuner and, using your current TV1 (IR) remote, enter the following in order:
1. "Menu"
2. "System Setup" (#6)
3. "Installation" (#1)
4. "TV1 UHF Pro Setup" (#6)
5. Now go to the left side of the screen, highlight "Enable," and hit "Select" on your remote.
6. Now go back to the right ("System Info" should be highlighted) and hit "Select" on your remote.
You should now be looking at the "System Info" screen.
7. Press the "Up" button on your remote twice until the box next to "Primary Remote Address" is highlighted in yellow.
Now, grab your "TV2" UHF (blue bottom) remote and follow this procedure:
NOTE: All steps from here on will use the TV2 (UHF) remote.
1. Hold down the "Sat" button (upper left corner of the remote) for a few seconds until all four of the top buttons light up. When they all light up, release the "Sat" button.
The Sat button should now be flashing.
2. Enter a number on the keypad of the remote. In can be any number between 1 and 16 but it MUST be different than the number that's in the lower box (next to "Secondary Remote Address"). If you do try to enter the same number, you will be prompted that it isn't allowed.
3. After entering your number, press the pound/search key "#" (lower right corner). Wait a second. The "Sat" button (upper left corner) should flash three times.
4. After the Sat button has finished flashing, press the "Record" button on the remote (near the middle, under the "Pause" button). The yellow box should now display the number you entered in step #2.
5. Press the "Down" button on the remote two times until "Done" is highlighted.
6. Press "Select" on the remote.
You are now controlling TV1 of your 522 with a UHF remote. Enjoy!
